You cannot just replace them unless you change all 4 door cards and tear the dash apart to get the one piece over the airbag considering its bolted from the back. You can wrap it with carbon fiber wrap which is getting popular and iv done it. Also ebay sells overlay kits i believe.

No. The product is re-positionable and very easy to work with. I'd suggest starting with the little piece of trim on the driver's side dash. That pops right out. Wrap that. Then maybe pop of the radio bezel and wrap that. Then you can start attacking the parts you can't remove, like the trim on the doors. It just takes patience. The more meticulous you are, the better it will turn out. Get a few cheap plastic putty knives, a sharp razor, and a hair dryer, and you've got all the tools you need to do the job.

Do they make it in anything other than carbon fiber? I was wanting to go with the brushed aluminum look. I don't think I'd like the carbon fiber with black interior.

I'm pretty sure they have other items too...but I know they have a ton of different carbon fiber colors as well. I know I saw a silvery/aluminum colored one on there when I was shopping. I even think they had camo...
